FMRI Studies of Visual Categorization in The Human Brain
Alexander Huth, et.al., at the University of California, Berkeley, have demonstrated how five human subjects, each viewing over two hours of movie clips, were each scanned by functional Magnetic Resonance Imaging instruments. Each brain scan recorded blood flow in thousands of individual locations, across their respective brains. Principal components analysis of regularized linear regressions revealed 1700 visual categories of 30,000 locations in cortex. Huth et.al. found highly organized, overlapping maps that occupied over 20% of cortex.

“Even the poor student studies and is taught only political economy, while that economy of living which is synonymous with philosophy is not even sincerely professed in our colleges. The consequence is, that while he is reading Adam Smith, Ricardo, and Say, he runs his father in debt irretrievably.”
—Henry David Thoreau (1817–1862)
“The visual is sorely undervalued in modern scholarship. Art history has attained only a fraction of the conceptual sophistication of literary criticism.... Drunk with self-love, criticism has hugely overestimated the centrality of language to western culture. It has failed to see the electrifying sign language of images.”
—Camille Paglia (b. 1947)
“It is certain that the only hope of retroductive reasoning ever reaching the truth is that there may be some natural tendency toward an agreement between the ideas which suggest themselves to the human mind and those which are concerned in the laws of nature.”
—Charles Sanders Peirce (1839–1914)
“Money is the last enemy that shall never be subdued. While there is flesh there is money—or the want of money, but money is always on the brain so long as there is a brain in reasonable order.”
—Samuel Butler (1835–1902)
